| Popis: | The reaction of tricarbonyl(exo-cyclopentadienyl-η5-cyclohexadienyl)manganese (1) with aryllithium reagents, ArLi (Ar=C6H5, o-, m-, p-CH3C6H4, p-CH3OC6H4, p-CF3C6H4), in ether at low temperature afforded acylmetalate intermediates, followed by alkylation with Et3OBF4 in an aqueous solution at 0°C to give the six alkoxycarbene manganese complexes [C5H5-{(η5-C6H6)(CO)2Mn=C(O-C2H5)Ar}] ( 2 , Ar = C 6 H 5 ; 3 , Ar = o- CH 3 C 6 H 4 ; 4 , Ar =m- CH 3 C 6 H 4 ; 5 , Ar = p- CH 3 C 6 H 4 ; 6 , Ar = p- CH 3 OC 6 H 4 ; 7 , Ar = p- CF 3 C 6 H 4 ) . The molecular structures of 2 and 3 have been established by X-ray diffraction studies. |
